摘　　要：通过静态试验研究了阴离子型表面活性剂LAS和非离子型表面活性剂AE对彭泽鲫的联合毒性影响。结果表明,LAS对彭泽卿的24h,48h,96h的半致死浓度LC50分别为10 20,8 73,8 43mg/L,AE对彭泽鲫的24h,48h,96h的LC50分别为87 98,72 54,68 90mg/L。LAS和AE共存对彭泽鲫联合毒性的24h,48h和96h时的相加指数AI分别为0 025,0 475,1 34,皆大于零,表现为协同作用。Joint-toxicity of anionic surfactant LAS and nonionic surfactant AE to carassius auratus var. Pengze was studied through a static test. It demonstrats that LC50 values of LAS to Carassius Autatus var.Pengze for 24h, 48h and 96h were 10.20, 8.73 and 8.43 (mg/l) respectively while those of AE were 87.98, 72.54 and 68.90(mg/l) respectively when the LAS and AE were coexistence, the results from the indexes show a kind of synergistic action.
